It may feel like your baby's sleeping all the time in the first few weeks -- and that's because he pretty much is. Your baby will sleep almost round-the-clock in the beginning. Over time, he'll go down longer at night with distinct naps during the day. Here's an overview of what to expect:

• Newborn to 3 months: 16 hours total, about eight at night and eight during the day

• 3 to 6 months: 14 hours total, about 10 at night and four during daytime naps

• 6 to 12 months: 14 hours total, about 11 at night and three during daytime naps

It's important to remember that these are just guidelines, so if your baby sleeps a little more or less, don't worry. As long as he's content, lively, and growing at a healthy pace, he's likely doing just fine.

Newborns (less than 2 months) sleep about 16-18 hours a day total, usually 3 or 4 hours at a time between feedings. My newborns never went longer than about 5 hours at this age. At 2-4 months, babies should sleep 4 hours between feedings but are awake a bit more, so total sleep is 14-16 hours a day. See this baby sleep chart for a full breakdown.
